Description
The G4IDC5-SW module provides one isolated channel of contact status input, sensing switch closure. The module supplies 15 volts of power to an external dry contact switch. Each user-supplied switch is connected with two wires. Because the module includes power for the switch, this module is particularly cost-effective when labor costs for wiring external power are high. Typical applications for the G4IDC5-SW include sensing contact closure from sources such as proximity switches, limit switches, selector switches, push buttons, photoelectric switches, and TTL-compatible devices. Opto 22’s G4 DC input modules provide up to 4000 volts (transient) of optical isolation between field inputs and the logic output of the circuit. CAUTION: G4IDC5-SW and G4IDC5-SWNC inputs are not intended to be used with contacts that are connected to any external user-supplied voltage or current.
